Thanks Rob.
It turned out that the last backup copy was bad, so I went back to the next oldest and uploaded it. I keep telling my wife that there is a method to my madness and part of the madness is keeping various historical backups.
That did get both the admin and the cart back online. My guess is that this whole episode may have been due to some flakiness in my internet connection that affected more than just the files that I was editing.
Thanks to all for your advice. It's this community that makes a difference.
